A battleship on tracks would still need close-defense weapons

What defenses could stop a tracked HMS Warspite or USS Texas used as an amphibious land battleship?

Its main weakness would be the close dead zone beneath its high-mounted guns, so it would need low-mounted weapons and armored escorts despite its heavy protection and firepower.

The imagined vehicle combines HMS Warspite or USS Texas with tracks for movement ashore. The battleship's main and secondary guns would leave a close dead zone because their mountings cannot depress far enough to engage targets beside the hull. Additional low-mounted guns and an accompanying armored formation would therefore be necessary. The hull's structure and enormous tracks might resist smaller mines, although the design would require major alteration rather than simply placing an existing ship on a chassis.
